How do you feel when Blood Sugar is too High

How High Blood Sugar Affects Your Body

High blood sugar, or hyperglycemia, is a condition that occurs when the level of glucose (sugar) in your blood is too high. It is commonly associated with diabetes, a chronic metabolic disorder affecting millions of people worldwide. But what exactly happens to your body when blood sugar is too high?

The Impact of High Blood Sugar

When your blood sugar levels are consistently elevated, it can lead to various detrimental effects on your body. One of the primary complications of high blood sugar is the increased risk of developing long-term health problems. High blood sugar can damage blood vessels and nerves, leading to complications such as cardiovascular disease, nerve damage (neuropathy), kidney disease (nephropathy), eye problems (retinopathy), and impaired wound healing, among others.

Symptoms of High Blood Sugar

Hyperglycemia can cause a range of symptoms, including increased thirst, frequent urination, unexplained fatigue, blurred vision, slow healing of cuts and bruises, recurrent infections, and weight loss despite increased appetite. However, it's important to note that some people with high blood sugar may not experience noticeable symptoms, which is why regular blood sugar monitoring is crucial, especially for those with diabetes or at risk for developing diabetes.

Mechanisms of High Blood Sugar

The presence of excess glucose in the bloodstream disrupts the delicate balance of glucose regulation in the body. In individuals with diabetes, this can be due to a lack of insulin production or insulin resistance, resulting in impaired uptake and utilization of glucose by cells. As a result, the glucose accumulates in the bloodstream, leading to hyperglycemia. High blood sugar can also trigger oxidative stress, inflammation, and other cellular and molecular changes that contribute to the development of complications associated with diabetes.

Glycemic Control and Management

Managing high blood sugar is essential for individuals with diabetes to prevent complications. This typically involves lifestyle changes such as maintaining a healthy diet, regular physical activity, weight management, and taking prescribed medications as recommended by a healthcare professional. Monitoring blood sugar levels regularly, as well as working with a healthcare team to optimize glycemic control, is crucial in preventing and managing high blood sugar levels.


High blood sugar, or hyperglycemia, is a condition that can have significant impacts on your body, especially if you have diabetes or are at risk of developing diabetes. It can lead to long-term health problems, such as cardiovascular disease, nerve damage, kidney disease, and eye problems, among others. Monitoring blood sugar levels regularly, adopting a healthy lifestyle, and working with a healthcare team are crucial in managing high blood sugar and preventing complications.
